The Escher’s Waterfall was just an artwork of optical illusion and perspective by the renowned Dutch artist in the last century. Until now, this artwork looks crazy on paper and almost impossible to create in real life but recently a German student brought it to life by creating a physical version of the waterfall that actually works. This impossible drawing shows what appears to be water running uphill before descending back onto a watermill wheel. Of course there is some sort of trick going on, but no one yet knows how to explain it, neither his creator wants to reveal the secret (despite hundreds of YouTube users begged him). The most popular and plausible explanation at the time is that there’s some sort of visual trick or computer special effects added in.
